No. 1 Simona Halep withdraws from final tuneup for U.S. Open

NEW HAVEN, Conn. -- Top-ranked Simona Halep has withdrawn from the Connecticut Open, citing a sore right Achilles tendon.

The Romanian was scheduled to play Tuesday in New Haven, but says in a statement her Achilles is sore from "two weeks of many matches and I need to recover in time for the US Open."

The New Haven tournament also lost American CoCo Vandeweghe to injury. She withdrew Sunday with a sore right ankle while leading in the third set of her first-round match with Magdalena Rybarikova of Slovakia.
